YouTuber Logan Paul posted video of a dead man who'd killed himself by hanging, and thought that was an okay thing to do. Of course, he's definitely at fault here – but so is YouTube, and it turns out the moderation team even saw, reviewed and decided to leave it up.

This is a twist that lays even more culpability at the feet of YouTube, which wasn't blameless even before this came to light. The platform is already facing criticism for its moderation practices in other areas, and this is bound to deepen that.

One of the final steps before launching a rocket is putting it vertically on its launchpad, and that's exactly what SpaceX has done with its Falcon Heavy. The big controlled explosive device has three Falcon 9 boosters strapped together for a tremendous amount of thrust, and it's likely to be quite the sight to see when it launches sometime this month for the first time ever.

Now it's doing whatever it can to save face.
